Episode description as stored
John Lindquist created egghead.io, a developer education platform used by hundreds of thousands of working engineers. These days he’s building mega.dev, a hands-on program specifically for developers who want to do real work with AI agents, not just prototype them. What you’ll learn: Why Jev is a decision engine, not a chatbot, and what that distinction actually changes about how you build How John built a real-time voice to-do app that classifies and executes commands with no visible pause The data deduplication pattern that merges messy records in milliseconds using confidence scores Why Jev works best as a router, and how a single text input can navigate users deep into an app What a chess match between Jev and a low-reasoning LLM reveals about speed, cost, and when to use which The multi-step classification pattern John reaches for when one Jev pass isn’t enough Where Jev falls short, and when you should still reach for a full generative model — Brought to you by: Vanta —Automate compliance and simplify security — In this episode, we cover: (00:00) John Lindquist returns for Jev week (04:32) What Jev actually outputs (06:15) Demo: real-time voice to-do app (08:17) How sequential Jev calls chain together (10:38) Demo: plain English to function name (grocery cart) (11:50) Demo: data deduplication and record merging (13:45) Confidence scores and multi-model validation (15:06) Demo: Jev as a multi-level app router (18:23) Architecting around Jev (19:35) Demo: Jev vs. traditional LLM at chess (speed and cost benchmarks) (24:29) DOM interactions as a decision set, not an infinite canvas (28:21) Demo: Wikipedia “path to philosophy” route mapper (30:28) Demo: multi-agent coordination and collision avoidance (33:36) Demo: real-time presentation coach (36:56) Quick recap (39:54) Lightning round and final thoughts — Tools referenced: • Jev (TypeSafe AI decision model): https://typesafe.ai/blog/introducing-system-one-models-and-jev • Vercel AI Gateway: https://vercel.com/docs/ai-gateway • OpenRouter: https://openrouter.ai • Opus 5.5 (mentioned in context of iterative demo building): https://www.anthropic.com/claude-opus-5-5 — Where to find John Lindquist: LinkedIn: linkedin.com/in/john-lindquist-84230766 X: https://x.com/johnlindquist Mega.dev: https://mega.dev/ Egghead.io: https://egghead.io/ — Where to find Claire Vo: ChatPRD: https://www.chatprd.ai/ Website: https://clairevo.com/ LinkedIn: https://www.linkedin.com/in/clairevo/ X: https://x.com/clairevo — Production and marketing by https://penname.co/ .
